Running pgTAP tests

The pgTAP tests can be found in subdirectories of Open-ILS/src/sql/Pg/
as follows:

t: contains pgTAP unit tests that can be run on a freshly installed
Evergreen database

live_t: contains pgTAP unit tests meant to be run on an Evergreen
database that also has had the "concerto" sample data loaded on it

To run the pgTAP unit and regression tests, use the pg_prove command.
For example, from the Evergreen source directory, you can issue the
command:
pg_prove -U evergreen Open-ILS/src/sql/Pg/t Open-ILS/src/sql/Pg/t/regress
